Many faults occur via the station ground system.? This fault indicated a
difference in potential between the station ground and the AC Mains
ground.? In many cases, the station equipment is connected between
station ground and the AC Mains ground.??
I think we're seeing monthly reports of KIO3 ports being blown up by
having it connected to a PC and creating a ground loop. I wonder why
this keeps happening over and over.
The proper solution is to have an entry panel through which EVERYTHING
is grounded and connected together. There have been a fair number of
publications on this over the years.
I do wonder though, if a full galvanic isolator would also help? It
won't replace the ground panel, but having heard the stories (followed
by "I need the KIO3 repaired and can't get parts / Elecraft repair is
backed up") I wonder about this measure.
How such an isolator box is powered would be another matter though. But
I wonder who tried this?
